Hydroxyapatite carbon fiber material, bone repair biological composite material, preparation method and application
The invention belongs to the technical field of carbon fiber composite materials, and provides a hydroxyapatite carbon fiber material and a preparation method thereof.The preparation method comprises the steps that carbon fiber cloth and an organic template react to obtain the carbon fiber cloth for constructing an organic phase, and the carbon fiber cloth is sequentially immersed into a soluble phosphate solution, a calcium-containing compound solution and simulated body fluid containing a surfactant; the hydroxyapatite carbon fiber material is obtained; the invention also provides a hydroxyapatite bone repair biological composite material and a preparation method thereof. It is found for the first time that cationic, non-and zwitterionic surfactants can accelerate the mineralization rate of hydroxyapatite, and hydrogen bonds are generated between hydroxyapatite and a polyaryletherketone resin matrix, so that the binding force between hydroxyapatite and the polyaryletherketone matrix is higher, falling is not prone to occurring, and the service life of hydroxyapatite is prolonged. The uniform and ordered hydroxyapatite bone repair biological composite material with excellent mechanical property, high biological activity and biocompatibility is obtained, so that the hydroxyapatite bone repair biological composite material fully meets the requirements of mechanical strength and biological environment required by implantation into a human body, and the application range of the hydroxyapatite bone repair biological composite material is expanded.
本发明属于碳纤维复合材料技术领域，提供一种羟基磷灰石碳纤维材料及其制备方法，将碳纤维布和有机模板进行反应，得到构建有机相的碳纤维布并将其顺次浸入可溶性磷酸盐溶液、含钙化合物溶液、含表面活性剂的模拟体液，得到羟基磷灰石碳纤维材料；本发明还提供一种羟基磷灰石骨修复生物复合材料及其制备方法。本发明首次发现，阳、非、两性离子表面活性剂能够加速羟基磷灰石矿化速率，在羟基磷灰石与聚芳醚酮树脂基体之间有氢键生成，使其与聚芳醚酮基体结合力更强，不易脱落，得到均匀有序的、具有优异力学性能、高生物活性和生物相容性的羟基磷灰石骨修复生物复合材料，使其充分吻合植入人体内所需力学强度及生物环境要求，扩大其应用范围。
